Thermal imaging roof survey in Aldenham, Hertfordshire
We carry out thermal roof surveys in Aldenham and the rest of Hertfordshire. Surveys run seven days a week.
- Heat escaping through the roof
- Cold areas below the roof
- Damp around chimneys and parapets
Before and after the survey
Over many surveys, some simple habits stand out as worth the effort:
- Keep the heating on as usual before a heat loss survey
- File the images with your roof records
- Keep a record of when stains appear
- Leave the roof to people with safe access
The report explains the conditions on the day and how they affected the images. That way you know how much weight to give each finding.
Check that loft insulation is laid evenly and hasn’t been pushed aside. Gaps often appear after work in the loft.
Thermal roof survey in Aldenham
Wet insulation under a flat roof covering holds heat for longer than dry. So a wet patch can show as a warmer or cooler area on the camera. It helps us see how far water may have spread under the covering, something you can’t normally tell from the surface. Moisture readings are then used to check what the camera suggests. We survey pitched roof slopes, flat roofs and commercial roofs, and common reasons people get in touch are thin or uneven insulation in the roof and damp patches with no obvious cause.
Villages like Aldenham often stand in open country, where wind can be strong. High wind or heavy rain stops a small drone flying, and calm conditions also suit thermal imaging best. The visit is planned around the forecast, along with the journey and access. A change in the forecast can mean moving the visit to another day.
What you get is a clear record of the roof on the day we saw it. It’s useful right away, and a good reference for later, for instance when you want to check whether anything has changed.

Aldenham questions
Is drone flying allowed in Aldenham?
That depends on where the roof is and on the weather. Aldenham is about 2 miles from Elstree Aerodrome, so the Drone Safety Map is checked for restrictions around it before we fly. High wind or heavy rain also stops a small drone flying, though the rest of the survey goes ahead either way.
Does a conservation area affect roof work in Aldenham?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Can you check my loft insulation with a thermal camera?
The camera can point to heat loss and gaps in insulation. The survey isn’t an energy rating or a heat loss calculation, but the report shows where to look more closely.
Can you do a thermal survey in any weather?
Conditions on the day affect the results. A sunny day beforehand, a dry surface and calm air all help. Rain, wind and heavy cloud can weaken the patterns, so we discuss the forecast when booking.
Does thermal imaging detect leaks directly?
No, not on its own. It shows surface temperature, and wet areas can show up because they hold heat differently. We confirm what it suggests with moisture readings.
How do I book a survey in Aldenham?
The quickest way is to call 07833 053749 or use the contact form. Let us know the address and a little about the roof, and we’ll point you to the right survey. We survey on weekdays, Saturdays and Sundays.
Do you climb onto every roof?
Not unless it’s safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed.
DIY checks: what’s safe
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
When you need someone else
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Reliable images in rain, strong wind or on a wet roof surface
- A formal energy assessment
- A structural engineer’s assessment
Not sure which survey suits your roof? You can phone 07833 053749 or send us an email and we’ll tell you. What a survey covers and does not.

- Ceilings below the roof
- Insulated roof spaces

Why act early in Aldenham
For buyers, a thermal survey adds detail that a visual inspection can’t give. Hidden problems found before exchange can be raised with the seller or agent. Matching old materials, like handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before you book.

When to book a survey in Aldenham
Some owners book because the rooms under the roof feel cold. Missing or slipped insulation can stand out as temperature differences, particularly when there is a clear difference between inside and outside.
Signs worth acting on include:
- Ceilings that feel colder in places
- Heat escaping through the roof
- Moisture around outlets and upstands
- Damp patches with no obvious cause
High Elms Manor, about 2.5 miles north-west, is one of the historic houses in the wider area around Aldenham. For older roofs nearby, a look from the air or with a thermal camera is a hands-off way to check condition.
Choosing a roof surveyor
- Is there a chance to talk the report through?
- What the survey will not cover
- Whether the loft is part of the inspection
- Their track record with similar roofs
How the survey works
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes between one and two hours for most homes, plus time to check any thermal findings with moisture readings. Cottages and farmhouses around Aldenham often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen, and anything we can’t see is noted.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- We carry out a visual inspection of the roof from wherever it can safely be seen.
- Thermal images are taken to show differences in surface temperature.
- We check the patterns that stand out with moisture readings where there’s safe access.
- We write up the thermal images alongside ordinary photos and recommendations.
Getting ready for the survey
- For flats, make sure roof access has been agreed
- If you’re buying, check with the agent that we can get in
- Check the loft hatch can be reached
Arrange a survey
When you are ready to go ahead, call 07833 053749 or drop us an email. From there it’s a case of choosing a package, agreeing the price and fixing a day, weekday or weekend.
Advice
Flying and imaging in Aldenham
Elstree Aerodrome is about 2 miles from Aldenham. If the drone is used for your survey, the Drone Safety Map is checked for restrictions first. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail.
If you run a business near Harlequin Centre, large commercial roofs are frequently easiest to see from above or with a thermal imager. Take a building like Fair Field Junior School: big roofs are where close-up aerial shots and thermal images show the most at once.
